Are Commercial Drivers Held to a Higher Standard of Care?

This distinction is often debated in both plaintiff and defense cases, where plaintiff's counsel typically argues that commercial drivers should be held to more stringent standards, while defense attorneys seek to mitigate this heightened scrutiny.

"Standard of care" in the legal realm refers to the level of care and responsibility expected of individuals in various professions. This standard can be explicit, through written regulations, or implied through accepted practices within the industry. In many legal cases, a central question revolves around whether an individual met the standard of care required in their field—whether that individual is a driver, a doctor, or a law enforcement officer. This standard helps determine whether a party is liable for damages or if they are absolved from responsibility.

Commercial drivers are held to a higher standard than those operating private vehicles due to their professional responsibilities. This is reflected in several key regulations and practices that apply specifically to individuals holding a commercial driver's license (CDL). Below are several key points that underscore the higher standards imposed on commercial drivers:

  1. Blood Alcohol Concentration (BAC) Standards: CDL holders are subject to a stricter BAC threshold of 0.04, compared to the typical 0.08 or 0.10 limit for non-commercial drivers. This lower BAC limit applies even when the driver operates their personal vehicle, as they may later drive a commercial vehicle.
  2. Drug and Alcohol Testing: CDL holders must undergo mandatory drug and alcohol testing. This includes pre-employment tests, random tests, post-accident tests, and tests based on reasonable suspicion. If a CDL holder is suspected of being under the influence, a test may be required to confirm or rule out impairment.
  3. Medical and Physical Requirements: Commercial drivers are required to maintain a valid Department of Transportation (DOT) physical examination. This examination includes rigorous assessments of blood pressure, heart rate, vision, hearing, and other physical capabilities. Drivers with medical conditions must be evaluated and certified annually by a medical professional to ensure they remain fit to drive.
  4. Training and Certification: Even experienced commercial drivers must undergo training whenever they change employers or roles. The Federal Motor Carrier Safety Administration (FMCSA) mandates that companies verify a driver's proficiency in 20 areas of operation, from vehicle inspections to handling adverse driving conditions and emergency maneuvers.
  5. Driver Qualification (DQ) File: CDL holders must have a comprehensive Driver Qualification (DQ) file maintained by their employer. This file includes detailed records such as a formal application, driving history, medical certifications, drug and alcohol test results, and traffic citations.
  6. Routine Inspections: Commercial vehicles are subject to regular and random inspections at weigh stations and roadside checkpoints. These inspections ensure compliance with safety standards, and non-compliance can result in a driver being placed out of service or facing legal consequences.
  7. Hours of Service Regulations: CDL holders are restricted by FMCSA regulations on the number of hours they can drive. Over-the-road drivers are allowed to drive for a maximum of 11 hours per day within a 14-hour window and then must rest for at least 10 hours before continuing. Additionally, drivers are limited to 70 hours of driving per week.
  8. Endorsements and Special Conditions: Certain endorsements, such as those for transporting hazardous materials (HAZMAT), impose additional restrictions. Drivers carrying hazardous materials, for instance, must stop at all railroad crossings and adhere to specific parking and routing rules. Non-commercial drivers carrying hazardous materials do not face the same requirements.
  9. Air Brake Systems: Commercial vehicles with a gross vehicle weight rating (GVWR) over 26,000 pounds require the driver to possess a CDL with an air brake endorsement. This is in contrast to non-commercial drivers who may operate vehicles with air brakes without the need for a CDL or additional endorsement.
  10. Broader Definition of Commercial Vehicles: The term "commercial vehicle" extends beyond large trucks. According to the American Society of Safety Professionals (ASSP) and the American National Standards Institute (ANSI), a commercial vehicle is defined as any vehicle used for business purposes, whether owned, leased, or rented by an organization. This includes vehicles like service vans, delivery trucks, and even company cars, all of which are subject to higher standards of care.
  11. Law Enforcement Authority: Commercial drivers are also subject to a greater degree of scrutiny by law enforcement. During routine traffic stops, officers have the authority to inspect a driver's documentation, including their license, registration, permits, and hours-of-service logs. This level of scrutiny is not typically applied to non-commercial drivers.
  12. Insurance Requirements for Commercial Drivers: Drivers who use their personal vehicles for commercial purposes, such as those working for Uber, Lyft, or delivery services like DoorDash must maintain specialized insurance coverage. This commercial insurance is distinct from personal auto insurance and ensures that the vehicle is covered during business-related activities.

In summary, commercial drivers are indeed held to a higher standard of care than non-commercial drivers. This heightened responsibility is enforced through a complex set of regulations designed to ensure public safety and minimize risks associated with operating large or business-related vehicles. The consequences of failing to meet these standards can be severe, including penalties, loss of employment, or liability for damages in the event of an accident.
